以南極光學雷達觀測及高精度數值模擬探討波動於高層大氣之影響及太空任務安全運作之重要性(2/2)

This proposal aims to address the factors impacting the operational integrity of space missions. Spacecraft safety requires constant monitoring and careful maneuvering. However, the dynamics of upper atmosphere is complicated by the forcing from above and below. Under certain circumstances, waves generated bysudden occurrence of such forcing dissipate and impact the energy balance of the upper atmosphere, resulting in variations of ambient temperature and neutral density. These variations make the tasks of tracking spacecraft difficult and challenging. Thus, a great care with high-resolution modeling is required to prevent catastrophic losses during space missions. We propose to use a highresolution model for the upper atmosphere to investigate the energy transport between the troposphere and ionosphere, and the impact to the ambienttemperature and density variations of the upper atmosphere by forcing from below. The development of programming capability is the first step toward our ultimate goal to ensure safe space missions and to develop Taiwan’s first highresolution upper atmospheric model that can run on a graphic card. We also propose to engage the general public to help monitor the troposphere for the upward propagating gravity waves.
